Networking and Firewall Rules for Distil Private Deployments

Provisioning Access (customer provided machines)

During provisioning, full outbound HTTP (TCP 80) and HTTPS (TCP 443) access is required. Additionally, inbound access from the Distil PCI Network (including port 22) is required during provisioning.  

Firewall Configuration

In order for your Distil Private Cloud Node(s) to participate as a member of the Distil PCI Network, you must configure your firewall to allow inbound and outbound connections as described in the table below:

Distil iDRAC access if Distil provides hardware.

Inbound

TCP and UDP

192.225.212.0/22
192.225.216.0/24

Distil iDRAC access if Distil provides hardware.

 

Inter Cluster Communication

Distil instances must be able to communicate fully with each other within a clustered configuration across all ports (TCP and UDP).

Remote Access

Distil Network Operations and Security team will require ongoing access to deploy, monitor, and manage the Distil instances. The firewall configuration above covers all remote access requirements.

Distil’s preferred mechanism for accessing Distil instances is via SSH on port 37281 to a public IP restricted to the Distil’s IP ranges. The public IP may then NAT to the private IP of the Distil instances.

If your corporate security policy requires vendors to access your environment only by VPN, work with your Distil Project Manager to establish the necessary accounts.
